Hennessey’s HPE700 Twin Turbo Corvette Conquers the Dyno

Hennessey’s HPE700 Corvettes are nasty. They’re the stuff of nightmares as far as the competition is concerned. The HPE700 Supercharged Corvette could be considered kind of a replacement for the ZR1 (not in production this year), and because it is Hennessey's 700-horsepower performance package incorporating the Eaton TVS R2300 supercharger, it may very well outperform a would-be ZR1.

But there is an option for those who are more a fan of turbochargers than superchargers. Hennessey also offers an HPE700 Twin Turbo Upgrade for the 2014 Corvette Stingray. While 100 HPE700 Supercharged Corvettes will be created, only 24 turbocharged HPE700 Vettes will roll out of Hennessey headquarters for the model year and each one will produce 707 brake horsepower.
So basically, Hennessey takes a plain old 2014 Corvette Stingray and injects it with a heavy dose of steroids in the form of twin ball bearing turbochargers, a fuel system upgrade, stainless steel inlet piping, turbo downpipes and exhaust system, dual wastegates, an air-to-air intercooler, and dual air induction filters. All of this is professionally installed before being dyno-tested at the Sealy, Texas headquarters, and performance-validated at the company's on-site test track, Lonestar Motorsports Park.

Also included in the package are HPE Engine Management Calibration, serial-numbered dash and engine plaques, Hennessey exterior badging, premium floormats, and carbon fiber door sills, and a one-year/12,000-mile limited warranty.

UPDATE: Hennessey will reveal the HPE700 at the Boca Raton Concours in south Florida on Friday, February 21. The C7 will be displayed in association with AutoNation at the Boca Raton Airport Hangar Party, which kicks off a weekend of fun. The turbocharged LT1 proved capable of 10.5-second e.t.'s at 135mph during testing on 20-inch drag radials. And the turnkey price is said to be nearly $120,000 (including the cost of the Stingray with 3LT or Z51 options).
